JST-A GAS DETECTOR

JST-A(W) GAS DETECTOR consists of detector and valve control manipulator.The detector is mounted on the ceiling of gas-used areas (such as kitchen) used to detect gas leakage and give out sound and light signal. The valve control manipulator is installed on the valve of the gas pipeline used to close the gas pipeline valve automatically when leakage is detected. The detector and the valve control manipulator are connected by the wireless signal instead of visible line (the decorated house can avoid the connecting line which will affect the house appearance and the installation is troublesome). It is suited for the areas with gas pipeline such as home, hotel, and apartment to detect safty. JST-A (W) Wireless Gas Leakage Self-closing Valve detector can monitor the indoor gas leakage (such as kitchen) continuously 24 hours a day. When gas leakage is detected,and the gas concentration reaches to 1/10-1/4 of the explosion limitation, the detector will send sound and light alarm signal to warn the user,at the same time, the valve control manipulator automatically close the valve and cut the gas resource quickly and reliably in order to avoid malignant accidents such as fire, explosion, suffocation and death efficiently. 1.
